Seismic Response Analysis for Different Slopes of Highway Roadbed
The influence factors of the dynamic response of roadbed structure are discussed in detail in this paper. These include dynamic characteristic of earthquake, properties of subgrade soil and geometric shape of roadbed structure. The distributions of amplification factor of peak acceleration, peak velocity, peak displacement and relative displacement are comprehensively analyzed under various roadbed slopes. Some useful conclusions that the distributions of amplification factor of peak acceleration, peak velocity, peak displacement increase gradually with the raising of height is gone. Conclusively, the growth is low at the bottom part of slope, the top is fast. The contour is dispersal by slope shoulder point as circle center approximately, and increases gradually on the pavement from inner to outside. The contour of relative displacement is the similar to the amplification factor of peak displacement. It reaches the maximum at lateral slope mass of slope upper part. In general, it growths faster at the low 1/3 of slope mass, and changes a little at the upper part 2/3 of slope body. They have a more significant mutation between the two parts. The approximate position of instability slip surface under the seismic action is revealed. So, the research results can provide some references for the anti-seismic design of roadbed structure.
